Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67770, here are decompositions:

7 + 67763 = 67770
11 + 67759 = 67770
13 + 67757 = 67770
19 + 67751 = 67770
29 + 67741 = 67770
37 + 67733 = 67770
47 + 67723 = 67770
61 + 67709 = 67770

Showing the first eight; more decompositions exist.
